I seem to recall a quote by one of the Absurdist playwrights in which he said that his plays were all essentially about "two people walk into a room," and then it's what happens to them that makes the interest. I'm not entirely sure that I would call it "cliche" as such, but I understand your general meaning.
I have to agree about "cliché", not quite being the appropriate way to put it. It would have been far more suitable for me to refer to it as being somewhat typical of the medium. It seems I actually used the word with the intention of that meaning, forgetting that it has negative connotations.
In essence that quote refers to what I was thinking, a small-scale play that is contained within a single set and shows the development of a small number of characters over a period of time.
The whole point of the ending is to really challenge the audience into thinking about the consequences. I'm not sure why it wound up being a one-or-the-other situation like it did, but I was pretty damn excited when I wrote it.
I think that's part of my problem with the ending: it lacks any degree of finality.
Yes you are, symbolically, destroying your universe but the actual ending feels like opening Schroedinger's box, only to find that the cat had left of its own accord; regardless of whether we "open the box", or not, we aren't given any answers.
I can see the ideal response to the endings, and do find them very interesting myself, but I'm left wondering what a general audience would think. You reach what appears to be the end of the play and then it just stops:
Are people going to sit uncomfortably and wait for something to happen?
Are you going to get applause?
How long will it be until someone works up the courage to end the play?
Arguably, though, none of these actually matter as, I presume, this script doesn't have to be brought to life. I do like the idea that your audience becomes a microcosm for humanity as a whole, as portrayed by Tyler, in that they have a particular expectation of how a play will end, yet here you are challenging it and asking them to end the play for you - something they're not used to. You are, in effect, looking for your Tyler, who can overcome their "petty little morals and religions", and make the decision no one else will to progress your play.
My problem is that the ending is less "I am become the destroyer of worlds", and more "Oh, it's over?".
I understand the reasoning for this, you want the audience to think rather than continue to moralise for them, but I can't help but feel that its a little anticlimactic.
